If one's pursuit would be to find every opportunity to thank, praise and fulfill his obligations to H'shem he would quickly realize that to be the source to achieve and receive his heart's desires. pg 415 Nefesh Hachaim When one prays for his suffering to stop he must remember that just as he would not ask the doctor not to proceed with bitter difficult remedies to an illness H'shem in His infinite knowledge has sent the Yesurim as the best medicine. Gate Two, Chapter 11 pg 90/91
